Application filed nn 19,1905. Serial In. 265.987.

BINDER, a citizen of the United States, resid-' ing at Duncannon, in the county of Perry and State of Pennsylvania, have invented a new and useful Rolling-Mill, of which the following is a specification.

This invention relates to means for retaining the stretchers in place between the coupling-boxes.

he principal object is to provide a simple and effective device of a novel nature which will hold the stretchers in place and yet may be easily and quickly detached and reapplied as often as found desirable or necessary.

A further object is to provide a device of the above character that is durable and is not deleteriously affected to any material degree by heat and water.

In the accompanying drawings, Figure 1 is a view, partly in elevation and partly in secti on, of a portion of a mill with one form of the novel retaining device in place. Fig. 2 is a cross-sectional view throu h the same. Fig. 3 is a perspective view 0 the retaining device, and Fig. 4 is a perspective view of a sli htly-modi fied form of construction.

imilar reference-numerals designate corresponding parts in all the figures of the drawings.

In the embodimentillustrated the usual rolls are designated 5 and are journaled in housings, 6 with their gudgeons or "Wabblers 7 disposed in opposing relation. Interposed between the gudgeons are spindles 8, connected in the usual manner thereto by coupling boxes or sleeves 9. blocks 10 are located between the boxes or sleeves 9 and may be of any suitable mate rial, being seated in the ordinary grooves or recesses 11 of.the spindles.

For the purpose of retaining the stretcherblocks in place a band 12 is employed, comprising substantially semicircular sections 13, hinged together, as shown at 14, each of the sections referably having one of the stretcher-bloclis 10, carried thereby and secured thereto by any suitable meansas, for instance, rivets 15. The free end of one of the band-sections is provided with an outturned lip 16, having an opening 17 centrally therethrough, while the corresponding end of the other section is also provided with an outstanding lip 18, which lip is preferably turned back and provided with a transverse slot 19.

The stretcherillustrated in Fig. 4, wherein the band-sections are designated 13 and are hin ed to- Fastening means in the form of a retaining latch-stem 20 slidably passes throu h the opening 17, said opening being of su' cient size to permit the swinging movement of the stem, and this stem has at one end a head in the form of an eye 21, that is adapted to interlock in the seat 22. formed by the rearwardl -turned lip 18, the-portion of the stem direct y adjacent to the head or eye detachably engaging in the slot 19.- A coiled spring 23, arranged on the stem, has one end bearing against the rear side of the lip 16. the ot er end being abutted against a washer 24, held in place on the rear end of the stem by nuts 25.

The manner in whichthe device is used will be clear to those skilled in the art. When the coupling boxes or sleeves 9 have been placed in position, the retainin -band 12 is clasped upon the spindle and the stretcherblocks 10 seated in the grooves 11. The free ends of the band are then looked together by the latch, as clearly shown in Fig. 3. The stretchers are thus efficiently maintained in position and the retaining means is not affected by the heat and water. To uncouple the mills, it is only necessary to disenga e the latch from the lip 18, whereupon the andsections may be swun upon their hinge, and thus the stretchers detached. The boxes ma thereupon be moved toward each other and the spindles disengaged from the udgeons or wabblers. Consequentl it wi be seen that the device is not only e cient, but is convenient to operate, is durable, and can be cheaply manufactured:

A slight modification of the structure is gether, as shown at 14. Each of t e sections is provided with an outstanding portion 15, forming a seat to receive a stretcher; otherwise the structure is the same as that already set forth, and a further description thereof is believed to be unnecessary.

From the foregoing it is thought that the construction, operation, and many advan tages of the herein-described invention will be a parent to those skilled in the art without irther description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A retainin device for holding stretchers on the couplings of rolling-mills, comprising a band having free ends, a device slidably mounted on one end and having a detachable engagement with the other end, and means for maintaining said engagement between the device and end of the band.

2. A retaining device for holding stretchers on the couplings of rolling-mills, com rising a band having free ends, and a late includin a stem having a longitudinal sliding and a ateralswingin connection with one end of the band, said atch also having a detachable engagement with the other end of the band. a a

3. A retaining device for holding stretchers on the couplings of rolling-mills, comprising a band having free ends, a latch having a sliding and swingin connection with one end and a detachab e interlocking engagement with the other end, and a sprin for effecting the sliding movement of the atch in one direction, said spring yieldingly holding the said latch in its said interlocked engagement. 7

4. A retaining device for holding stretchers on the couplings of rolling-mills, comprising a band having free ends provided with outturned lips, one of said lips having a slot, the other havin an opening, a latch-stem slidabl mounte in the opening of the one lip an having a head that detachably engages the other lip, the stem detachably en gaging in the slot thereof, and a spring engaging the stem for maintaining the head in engagement with the lip.

5. A retaining device for holding stretchers on the couplings of rolling-mills, comprising a band composed of sections, a hinge connecting the corresponding ends of the sections, the free ends of said sections being rovided with outturned lips, one of whic is rearwardly turned to form a seat, said rearwardly-turned lip having a slot and the other lip having an opening, a latch-stem slidably mounted in the opening and ar ranged to engage in the slot, said stem having an eye at one end that detachably engages in the seat, and a coiled s ring located on the stem for yieldingly maintaining the eye in the seat.

6. In a rolling-mill, the combination with a band arranged to surround the couplingspindle and comprisin hin edly-connected sections having free en s, of astening means carried by one of the free ends and detachably engaging the other free end to thereby secure the band upon said spindle, and stretcher-blocks connected to and'carried by the diflerent sections of the band.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
